MUSIC-RACK AND LEAF-TURNER.

Specification in? Letters Patent.

Application filed December 27, 1909. Serial No. 535,030.

To all whom it may concern 'Be it known that 1, CHARLES S. GLIZBE, a citizen of the United States, residing at Ainsterdam, county of Montgomery, and State of New York, have invented certain new and useful Improvements in Music-Racks and 'Leaflurners of which the followin is a specification.

The invention relates to such improvements and consists of the novel construction and combination of parts hereinafter de scribed and subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein.

Figure 1 of the drawings is a view in side elevation of my improved music-rack and leaf-turner showing one of the leaf-turning arms inmid-position. Fig. 2 is a similar view of the lower part of the same on a larger scale, and shown partly in central, vertical section. Fig. 3 is a cross-section of the same taken on the broken line 8-3 in Fig. 2. Fig. A is a view in side elevation on an enlarged scale of the rocker-arm for operating the leaf-turning arms. Fig. 5 is a horizontal crosssection of the same taken on the broken line 55 in Fig. 1. Fig. 6 is a view on a larger scale than Fig. 1, of the upper portion of the device as seen at an angle of 90 degrees to the plane of the mus c-rack. Fig. 7 1s a cross-section taken on the broken line 7-1 in Fig.1. Fig. 8 is a view in perspective of the outer end of one of the leaf-turning arms. Fig. 9 is a central vertical section taken through the telescoping rock-shaft whereby the leaf-turning lines, in the usual manner.

arms are operated.

The principal object of the invention is to conveniently support. and turn the leaves of sheet or book-music.

Other objects will appear in connection;

with the followin description.

Referring to the drawings wherein the: invention is shown in preferred form, 1, repi resents a'hollow post adapted to be supportf ed in vertical position by means of folding 1 legs, 2, each pivotally connected at its up per end with a sleeve, 3, adapted to slide upon the post, 1, and having a tapered screw-threaded portion adapted to receive the thumb-nut, 4, whereby said sleeve may be clamped in adjusted position upon the post 1. Each said legs, 2, is connected with the lower end of the post, 1, by means of a link, 5, pivoted at one end to the lower end of the post, and at its other end to an intermediate part of the leg 2.

The post, 1, is preferably made up of telescopic sections, as shown in Fig. 1, the upper of said sections being designated, 1", and adapted to slide Within the lower main section, which lower main section, 1, has a tapered screw-threaded split upper end, 6, adapted to be clamped upon the section, 1, by means of a thumb-nut, 7, fitting said tapered screw-threaded port-ion. By loosen-- ing the nut, 7, the sections, 1 and 1*, can

be drawn apartor forced together to vary the length of 'the post formed thereby, and can be locked by the nut, 7, in the selected position. Upon the upper end of said vertical post is fixed an offsetting-head, 9, upon which is pivotally mounted at, 10, a music-rack, 11, adapted to support bookmusic or sheet-music opened or spread out to the view of a musician using the device. The rack thus pivotally mounted is adapted to be supported at the'proper angle for use by means of a spring-latch, 12, carried by the main-frame member of the rack and adapted to enter a suitable aperture in the stud, 18, fixed upon a bracket, 14, rigidly mounted upon the head 9. When, by manipulation of the latch, 12, t-he rack is released from the stud, 18, the rack can be swung back to a position substantially parallel with the post, 1, as indicated by dotted lines in Fig. 1.

As shown in Fig. 6, the rack is made up of pantographic members adapted to be folded to the position indicated by dotted lines, or expanded to the position shown by solid I pivotally mount upon the' stud, 13, one or more leaf-turning arms, 15, each having 5 means for embracing a leaf of sheet or bookmusic.

As shown inv Figs. 6 and 8, the arm, 15, is formed with achannel, 1.6, adapted to receive the bottom edgeof thegleaf, and with a pair of wire-fingers, 17, adapted to embrace between them the upper portion of the leaf. As shown, the arms, 15, swing on an axis which is parallel with the plane of the rack, 11, and oblique to the axis of the post 1., Any desired number of leafturning arms, 15, may be thus rotatively mounted upon the'stud, 13, the hubs of said arms being loosely confined on said.stud by shaft, 22, which is rotatively mounted in the hollow post formed by the sections 1 and 2.

As shown in Figs. 6 and 7, the rock-shaft, 22, is located slightly to the right of a vertical plane passing from front to rear through the stud, 13, so that the arc traversed by the yielding latch, 20, when the shaft, 22, is rocked is eccentric to the path traversed by the downwardly-projecting finger, 19, on a leaf-turning arm. The eccentric relation thus established between the leaf-turning arm and the latch, 20, is such that the latch, 20, is adapted to engage, yieldingly pass, and interlock with, a depend ing finger, 19, of a leaf-turning arm when the shaft, 22, is rocked to the right, as seen in Figs. 6 and 7, and to'pass out of engagement with said finger, 19, and release the same just before the tinger, 19, reaches the limit of its swinging movement to the left, gravity and the inertia of the moving leafturning arm being'suflicient to complete its swinging movement, thus making it possible for the latch, 20, to be returned to position to engage and interlock with'the next leafturning arm to be operated, without in its return movement engaging any of the leafturning arms which occupy a position at the lefthanol side of the rack.

As a means for operating the rock-shaft, 22, from time to time in the various relative positions of the post-sections, 1 and 1, I have shown said rock-shaft flattened on one side, as at, 28, and adapted to fit within a tubular shaft-extension, 22*, having its upper end flattened on one side at, 23 whereby a telescopic movement of the parts, 22

and 23, is permitted, while said parts are locked together with regard to rotative movement. The lower end of the shaft-sec tion, 22, is fixed to a shaft-sectimi, 22", provided with a spiral-groove, 24-, adapted to receive a pin, 25, fixed upon a sliding sleeve, 26, and adapted to play in a vertically elongated slot, 27, formed in the post-section, l,

as shown in Fig. 2. The sleeve, 26, is yieldingly supported by a coil-spring, 28, and has projecting from its lower-end a toot-rest, 29, whereby the sleeve can be depressed against the force of the spring 28.

l he rocker-arm, 21, normally occupies a position at the limit of its rocking movement to the left, as indicated by dotted lines ing apparatus the book or sheet-music is placed upon the rack with a leaf to be turned extending toward theright and inserted in one of the leaf-turning arms, which occupies the position shown by solid lines in Fig. 6.

The user of the device, when it is desired to turn said leaf, simply presses downward with his foot upon the foot-rest, 29, thereby forcing the sleeve, 26, and pin, 25, downward, the downward passage of the pin, 25, along the spiral groove, 24, serving to partly rotate the shaft-sections, 22 22 and and thereby cause a rotative movement from left to right of the rocker-arm, 21, causing its latch, 20, to engage the linger, 19, on said leaf-turning arm, or, if there be more than one of said leaf-turning arms, to engage the uppermost thereof. As soon as the user removes his foot from the foot-rest, 29, the

spring, 28, automatically forces upward the sleeve, 26, and pin, 25, causing a reverse movement of the rocker-arm, 21, which serves to carry the engaged leaf-turning arm from the right to the left.- Thus by successive applications of the foot of the user to the foot-rest, 29, the successive leaf-turning arms, if a plurality be employed, can be operated at the will of the user.

The yielding latch, 20, may be of any' known form, a preferred form thereof being in a chambered slideway in the rocker-arm in engagement with a coil-spring, 31, and

having its movement limited by a screw, 32, inserted through the wall of said slideway, and occupying a slot or groove in the side of said bolt.

I have shown the rack provided on its opposite ends with rotatively mounted offset wire-fingers, 34, adapted to overhang and hold down the surplus leaf or leaves when the book or sheet-music consists of more leaves than are to be automatically turned by the apparatus. The wire-fingers, 34, are pivotally mounted upon the outer ends of arms, projecting beyond the side-members of the rack, and are thereby given capacity for use with book or sheet-music of greatly different sizes. By having these fingers offset as shown at, 36, the fingers are adapted to engage by their extreme swinging ends the leave or leaves to be held down .9 shown 1n Figs. 4: and 5, wherein the latch is upon the raclvalthough the same may be of ctmsiderahle thickness, and to clamp said loaves between said finger and said rack. This feature of my invention adapts the rack for supporting book or sheet-music for use, whether or not the leaves are to be turned by the foot-operated apparatus.

The wire fingers, 17, which are adapted to embrace between them a leaf to be turned, are 'iivotally mounted at their lower ends at, I57, upon the leaf-turning arm which is in Figs. (3 and 7, and in using the lcat-iurir l formed with a head or flange, 38, along its can be r mits them to be SPILED out oi one notch, 39,

and into another when desired.

For storing or transporting the device, the legs, 2, can be folded substantially parallel with the post, 1'; and the rack, 11, can be folded l swung back substantially parallel with first, and the leaf-turning arms noved from the stud, 13, permitting the apparatus to be packed in a c0rnparatively small space.

For c in returning one or more of the l .o{; arms into position to be the leaf turning mechanism Feed, I have shown the channeled of the leaf-turning arms or" difien near their ends, so that when a o:.; the arms resting upon the side the rack, each up 2 arm pr near it a greater downward projection as at, 40, than the next, lower or s bjaceut arm, the leaf-turning arms thus h- 'r liver edge-portions of successively downward projection the order said arms are operat d by said The user of the devi e can thus. (3 lily turn from left right the uppermost arm byengaging with his linger the downwardly-projecting end-portion, 46, thereof. lit, however, he wishes to return all of the arms he can readily do so by en gaging with his finger the lowermost arm a point somewhat nearer the axis of ro-' tation, at which point all of the arms are of substantially the same height.
